jeff: throwing metal quads like dice for stakes

To jeff is to throw em quads (the smallest units of metal type, roughly 1/2 inch square) across a composing room surface as a gambling game. Compositors would stake money or shop credit on the outcome, with quads landing face-up or face-down determining winners. The practice was widespread enough in letterpress shops to earn its own term, though management universally discouraged it as both a waste of time and a source of workplace tension.

The game exploited the physical properties of quads themselves. Because quads were uniform metal blocks used as spacers in type cases, they were readily available, expendable, and had enough weight and flat surfaces to tumble unpredictably. A compositor could pocket a handful from the job case without immediate notice. The game required nothing else: a flat surface, quads, and agreement on stakes.

Why it happened and why it mattered

Compositors in the hot metal era worked long hours under piecework or hourly wage systems, often in competitive or monotonous conditions. Jeffing offered brief distraction and a chance at small winnings. However, lost time meant lost productivity, and lost money created grievances that could destabilize shop morale. Union rules and shop regulations gradually formalized prohibitions against gambling. By the decline of letterpress printing in the 1960s and 1970s, the term had already become historical.

The origin of the word itself remains unclear. Some sources suggest it derives from an old proprietor's name or a regional slang term for dice games, but no definitive connection has been established. The term appears in trade memoirs and union records but rarely in formal printing manuals, marking it as insider vocabulary rather than official technical language.
